Tracing the Geographical Origin of Durum Wheat by FT-NIR Spectroscopy

Rapid Analysis of Deoxynivalenol in Durum Wheat by FT-NIR Spectroscopy

Fourier-transform-near infrared (FT-NIR) spectroscopy has been used to develop quantitative and classification models for the prediction of deoxynivalenol (DON) levels in durum wheat samples. Partial least-squares (PLS) regression analysis was used to determine DON in wheat samples in the range of <50-16,000 µg/kg DON. The model displayed a large root mean square error of prediction value (1,97...

Discrimination Of Radix Pseudostellariae According To Geographical Origin By FT-NIR Spectroscopy And Supervised Pattern Recognition

Radix Pseudostellariae is one of the most popular Traditional Chinese Medicine (TCM) for promoting the immune system, treating asthenia after illnesses with a long history in China and some other Asian countries. Rapid discrimination of R. Pseudostellariae according to geographical origin is crucial to pharmacodynamic action control. FT-NIR spectroscopy and supervised pattern recognition was at...

Quantitative Analysis of Panax ginseng by FT-NIR Spectroscopy

Near-infrared spectroscopy (NIRS), a rapid and efficient tool, was used to determine the total amount of nine ginsenosides in Panax ginseng. In the study, the regression models were established using multivariate regression methods with the results from conventional chemical analytical methods as reference values. The multivariate regression methods, partial least squares regression (PLSR) and ...
